My invention relates to devices for handling preserving jars'of the wellknown type made usually of glass formed with a reduced diametral neckwith exterior threads adapted to receive ametal cap. These types of jarsin variablesizes are usually provided with but one size of opening andstandardized thread means. The main body of such jars is usuallyround incross section but some are made square in cross section with generouslyrounded corners as shown in Fig. 4, but my device is adaptable for useon either type. 7

The main object is to provide handling means ofclamp type, readilyplaced around the bodyof a jar below its threaded open-' ing and furthermeans of liketype readily engaging the exterior threaded part of a metalcap, the two devices cooperating m use when placing a cap on the jar orremovingv such cap.

In the accompanying drawing,- Fig. 1 is a top view of a round typepreserving jar of the class mentioned, with its cap in place, and myimproved clamp means in operative position.

Fig. 2 is a front view. of Fig. 1. Fig. 3 is an enlarged transversesectional view as on line 33 in Fig. l and including parts as above line44 in Fig. 2 only.

Fig. 4 is a modified sectional view as on line 4.4 in Fig. 2 showing ajar of the type which is approximately square in cross sec tion and ajar clamp of corresponding form.

Fig. 5 is an enlarged detail sectional view of the upper right handpartof Fig. 3 as between the lines-AA, more clearly illustrating certaindetails of the jar-cover clamp.

y improved jar and cover handling means comprises a pair of clampmembers one to engage a jar cap and the other to engagethe jar body.Both are alike in action; namely,

that their handles are squeezed toward each other to cause the clampparts to frictionally engage the ar cap and jar body, as will now befully described.

Then turning the cap by cloc wise movementthe cap is brought down as tight as necessary. Theflange 10F of thehandle prevents flange 8F from curling upi 'wardly or becoming uneven.because of pressure exerted. The cap handling device is 7 then easilyremoved by simply spreading it. Removal of a cap is accomplished by areverse action to that just'described. w
